Three other people who were injured in the crash, which happened in Bromley Road at about 8.20am on Sunday, February 26, remain in hospital, while a fourth person, a 36-year-old man has been discharged.

A 25-year-old man is in a critical condition, a 35-year-old woman is described as serious but stable and another man, aged 46, is being treated for a leg injury.

Witnesses described scenes of “carnage” after the crash as passers-by rushed to help those mowed down by the car.

The smashed-up car was left embedded in a bush beside Catford bus garage as a swarm of emergency services vehicles descended on the area.

Minasu Towolawi, 26, was on her way to church with her family when she heard screaming coming from near the car wash.

She told the Standard: “I went up there and I just saw carnage. There were two men lying flat on their backs there.

“There was another lady was being sat upright and people were trying to get her awake. She looked gone to me. They were all just wailing and crying.”

She added: "There was a lot of blood as well. I didn't notice the car until I came back afterwards. I just thought they'd been stabbed or shot."

Ms Towolawi said she believed those who were injured work and live at the car wash, and that they had been waiting outside for customers when they were hit.

She claimed several of the men started running after the driver, yelling: “F*** you. Why have you done this?”

“One of them was injured and bleeding from the forehead and was chasing the guy,” she said.

“I was so shocked,” she said. “I thought they were dead.

“It was horrific. I was really moved because everyone there was so upset. They were slapping themselves and were distraught.”

The car's bonnet and boot were popped open by the impact of the crash, and its airbags all deployed. Debris was left strewn across the pavement.

The car was towed away once the crash site was cleared.

Police said the driver of the car, a 23-year-old man, was detained at the scene by an off-duty police officer before being arrested on suspicion of causing serious injury by dangerous driving.

He was also arrested on suspicion of drink drive before being taken to hospital with a head injury.

The man was later taken to a south London police station where he was bailed to a date in early May pending further enquiries.

Detectives from the Met's Roads and Transport Policing Command are investigating.
